So If I file from the US, then the issue becomes how long it will take to get the biometrics appointment.
------------------correct
If I get the biometrics letter while I am abroad I will need to come back to get fingerprinted, right?
--------------------Correct
Is there any issue if I am abroad when the biometrics letter is issued?
---------------------No issue You can be out of US but the biometrics letter will be sent to US address and somebody should inform you that your biometrics appointment has arrived and date for biometrics is......
I will have it shipped to my US address ( I will maintain residence here).
On a side note! How many times do we have to be fingerprinted as immigrants here??!!? What is the purpose of all this? Is to make more money? To make our lives more miserable? To check whether I had become a felon since last time I was fingerprinted? Anything else? Just think about the amount of overhead this adds to the system.
